I made a browser video tool that puts text behind people in your shot, no green screen or rotoscoping

I'm not trying to go head to head with Premiere or Resolve. Those are great at full editing and I'd lose that fight. V8eo does a smaller set of specific things that are weirdly painful in the big editors, and it does them free in the browser. The feature people react to most is placing text behind a person or object in your video. It masks the subject automatically, frame by frame, so no rotoscoping and no green screen. You just click whatever you want the text to sit behind and it figures out...

I built an iOS app that turns my kid into the hero of their own bedtime story, and I want to be honest about the AI part

Bedtime in our house hit a wall. My kid wanted a new story every night, and "the one about the dragon, but different" is a tough brief at 8pm when you are exhausted. So I built the thing I wished existed. What it does: - You make a profile for your child (age, the stuff they love, a pet, a best friend) and they become the main character. - You get a fresh personalized bedtime story in a few seconds, tuned to their age. - You can steer it: set the theme, and just as importantly,...

My girlfriend hated me (kind of) so I made an app last weekend to fix it

My girlfriend hated when I made her pick places to go out. And I don't really know too many places around the city (me dev. outside bad πŸ™‚β€β†”οΈ). So I built this last weekend. Spots scrapes popular review channels on TikTok and displays the results all in one place. You can save a spot, make a list of all the places you've been to with notes and reviews, and you can see what other people have said about places. And the best part is that you don't have to be on TikTok to find cool places ...

I built an offline screenshot search app because I didn't trust the ones that upload your photos to the cloud

quick background: I screenshot everything to "check later" and never do, so it piles up by the hundreds and I can never find anything. I just wanted to search the text inside my screenshots. the apps that already do this mostly run the OCR in the cloud, so your photos get uploaded somewhere you don't control. I didn't want that, so I made the whole thing run on-device. the OCR and search are fully offline, no tracking or analytics SDKs, crash reporting off by default. the only backen...

i built a fake break room where the strangers are real

had this stupid idea stuck in my head: a place to clock out of a job you don't have. so i built it. you tap a punch clock, it ka-chunks, and you get a 3 minute break in a sad little corporate room with whoever else is currently on break. you can drop one anonymous line on the wall. then you leave with a canvas "receipt of nothing": 0 tasks completed, 3:00 of nothing reclaimed, no managers notified. the one part i cared about getting right: the live people count is real. no bots, no...

Made a free, open-source Mac menu-bar app that bundles a bunch of small utilities. What should I add next?

Hey all, I kept collecting tiny single-purpose menu-bar apps. One to keep my Mac awake, one for my hosts file, one for focus-follows-mouse. My menu bar slowly turned into a mess. So I built Quiver: one menu-bar icon that holds a bunch of small utilities you can flip on and off individually. Free, open source, no account, no telemetry, pure Swift/AppKit, stays out of the Dock. It bundles five right now: Follow Focus: focus-follows-mouse, so the window under your pointer raises and focus...

I built a tool to run Apple Search Ads the tedious-but-correct way β€” one keyword per campaign. Here's it managing 126 campaigns for my own app.

I make iOS apps, and Apple Search Ads has always been the most frustrating part of growth for me. The platform has basically zero automation β€” you can only create campaigns and change bids by hand, one at a time, in their dashboard. The "correct" way to run ASA is one keyword per campaign with exact match, because then you can see exactly which keyword makes money instead of everything being blended together. But nobody does this, because managing dozens or hundreds of separate campa...

I built a privacy first mobile dock which connects with my PC, provides me with quick access buttons for different apps and change my lights based on what I'm doing and yes it has offline voice support.

Recently I got my new desk and I started to customize things, so I made this Dock app + Rust based engine( I used cursor for the app since I'm not much into kotlin), the app is built like a standby Dock which can provide me quick access buttons based on what app is opened. It also changes the lights of my setup based on what kind of task I am doing( it identifies the tasks automatically) + recently I added voice command feature to this to do basic commands like opening things, playing music sear...

I made a community app that will have a focus on maximizing the way you want to express yourself!

Hey, I'm Fernando, the solo dev of a community app called Acid . I believe that Reddit and Discord are great, but neither of them was built for the way people like to express themselves. Reddit is mostly text-first and visually flat. Discord is great for chat, but treats long-form content as an afterthought, and Tumblr's tools have stagnated. Acid is an app that respects how people actually want to share. with customization, post types, and tools that make text feel like a creative artifact...

Learned the hard way: Building for a problem you don't feel yourself is a recipe for failure (my pivot story with Xoru)

Hey folks, wanted to share a pretty big lesson I learned recently. I launched a "content toolkit" a few months back – URL shortener, caption generator, storefront. Seemed like a solid idea for creators. Got traffic, which was exciting. But then I saw the data: most of the URL shortener usage was straight-up spammers. And the actual users? They'd sign up, try one tool, and just... leave. Zero stickiness. It hit me: I wasn't solving a problem *I* felt. I was building what I *though...
